To use the Chain Rule for finding derivatives in parametric form, you need to follow some simple steps.

First, start by understanding your parametric equations. These are usually written as:

• (x = f(t))
• (y = g(t))

Here, (t) is a parameter that helps connect (x) and (y).

Next, to find the derivative (\frac{dy}{dx}), we apply the Chain Rule. This means you can write the derivative in terms of (t) like this:

[ \frac{dy}{dx} = \frac{dy/dt}{dx/dt} ]

In this formula, (dy/dt) is the rate of change of (y) with respect to (t), and (dx/dt) is the rate of change of (x) with respect to (t). This step is the heart of the Chain Rule — it shows how the changes in (y) and (x) are related through the parameter (t).

Once you find these derivatives, try to simplify your expression. You might need to rewrite the fractions or factor out common parts. This will help make things clearer.

Lastly, take a closer look at your results in relation to the original problem. You might want to:

• Check the derivative at specific points
• Discuss what the sign of the derivative means (whether (y) is increasing or decreasing)
• Think about how these results relate to the shape of the curve made by ((x(t), y(t))) on a graph.

By following these steps, you can effectively use the Chain Rule with parametric equations!
